Remarks

If param_Present_flags = 0, Present spins without returning an error until the hardware is free.

If param_Present_flags = Present.DoNotWait and the hardware is busy processing or waiting for a vertical sync interval, the method throws a WasStillDrawingException.

If param_Present_flags = Present.LinearContent, gamma correction is performed from linear space to sRGB for windowed swap chains. This flag takes effect only when the Caps.DriverCaps.SupportsLinearToSrgbPresentation property is set to true.

The Device.Present method is a shortcut to SwapChain.Present. The swap chain method has been updated to include a flag that allows the application to request that the method return immediately when the driver reports that it cannot schedule a presentation.

If necessary, a stretch operation is applied to transfer the pixels in the source rectangle to the destination rectangle in the target window's client area.

The Device.Present method fails if it is called between a Device.BeginScene ... Device.EndScene pair, unless the render target is not the current render target (for example, the back buffer that results from the creation of an additional swap chain).

Exceptions

DriverInternalErrorException

Internal driver error. Applications should generally shut down when receiving this error.

DeviceLostException

The device is lost but cannot be reset at this time. Therefore, rendering is not possible.

InvalidCallException

The method call is invalid. For example, a method's parameter might contain an invalid value.

OutOfVideoMemoryException

Microsoft Direct3D does not have enough display memory to perform the operation.

OutOfMemoryException

Direct3D could not allocate sufficient memory to complete the call.
